In concept artwork, this character was referred to as "Quills", whereas the name "Hider" was applied to Fi'Ja.  In Prosthetics magazine (issue 5, pp. 12, 15), this character was again called "Quills", though the same publication referred to Zavanko as "Hider Zavanko".  A picture on Fraser Aitcheson's Instagram account identifies this character as the one he played in Star Trek Beyond.
